Quality Control

Our 9-Octadecenoic Acid (9Z)-, (9Z)-9-Octadecenyl Ester is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) are provided with each shipment, documenting critical parameters such as assay, acid value, and peroxide value to guarantee consistency and reliability for your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve quality. Keep away from strong oxidizing agents and heat sources.
